English: Diagram illustrating the basic internal parts of a 3.5" floppy disk. Document labels rendered as numbers to aid in internationalization. Note: The unlabeled square in the upper left is the approximate location of the write protection tab.
For IBM-compatible floppy controllers, a twist in the cable reverses the order of conductors 10 through 16 for the second connector. This allows two drives connected to the same cable to be addressed by the host controller without having to select drive assignments with jumpers on the drives themselves.

8-inch floppy disk, inserted in drive, (3½-inch floppy diskette, in front, shown for scale) 3½-inch, high-density floppy diskettes with adhesive labels affixed The first commercial floppy disks, developed in the late 1960s, were 8 inches (203.2 mm) in diameter; [4] [5] they became commercially available in 1971 as a component of IBM products and both drives and disks were then sold ...
When the controller and disk drive are assembled as one device, as it is the case with some external floppy disk drives, e.g., Commodore 1540 and USB floppy disk drives, [27] the internal floppy disk drive and its interface are unchanged, while the assembled device presents a different interface such as IEEE-488, parallel port or USB.
A disk controller is a controller circuit that enables a CPU to communicate with a hard disk, floppy disk or other kind of disk drive. It also provides an interface between the disk drive and the bus connecting it to the rest of the system. [1] [2] Early disk controllers were identified by their storage methods and data encoding.
In computing, label is a command included with some operating systems (e.g., DOS, [1] IBM OS/2, [2] Microsoft Windows [3] and ReactOS [4]). It is used to create, change, or delete a volume label on a logical drive, such as a hard disk partition or a floppy disk. Used without parameters, label changes the current volume label or deletes the ...
A disk operating system (DOS) is a computer operating system that resides on and can use a disk storage device, such as a floppy disk, hard disk drive, or optical disc.A disk operating system provides a file system for organizing, reading, and writing files on the storage disk, and a means for loading and running programs stored on that disk.
